Cov haujlwm thiab kev siv ntawm diethanolamine

Diethanolamine (DEA) yog ib qho organic compound nrog cov tshuaj formula C4H11NO2. Nws yog ib qho kua tsis muaj xim lossis siv lead ua uas yog alkaline thiab tuaj yeem nqus cov pa roj xws li carbon dioxide thiab hydrogen sulfide hauv huab cua. diethanolamine ntshiab yog ib qho khoom dawb ntawm chav tsev kub, tab sis nws nyiam deliquesce thiab supercool ua rau nws qee zaum zoo li ib qho kua tsis muaj xim thiab pob tshab. Diethanolamine, ua ib qho amine thib ob thiab diol, muaj ntau yam kev siv hauv kev tsim cov organic. Ib yam li lwm cov amine compounds, diethanolamine yog weakly basic. Xyoo 2017, Lub Koom Haum Kev Noj Qab Haus Huv Ntiaj Teb Lub Koom Haum Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kab Mob Cancer tau tshaj tawm cov npe ua ntej ntawm cov carcinogens, thiab suav nrog diethanolamine hauv cov npe ntawm Qeb 2B carcinogens. Xyoo 2013, cov tshuaj no kuj tau raug cais ua "tej zaum carcinogenic rau tib neeg" los ntawm Lub Koom Haum Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kab Mob Cancer.

Cov haujlwm thiab kev siv ntawm diethanolamine

1. Feem ntau siv ua cov tshuaj nqus roj acid, cov tshuaj surfactant uas tsis yog ionic, cov tshuaj emulsifier, cov tshuaj txhuam, cov tshuaj lim roj rau kev lag luam thiab cov roj nplua nyeem xws li CO2, H2S thiab SO2. Iminodiethanol, tseem hu ua diethanolamine, yog ib qho nruab nrab ntawm cov tshuaj tua kab glyphosate. Nws yog siv ua cov tshuaj lim roj thiab ua cov khoom siv raw rau cov tshuaj synthetic thiab cov organic synthesis.

2. Diethanolamine yog ib qho nruab nrab hauv kev tsim cov organic. Piv txwv li, nws tuaj yeem siv los tsim qee cov neeg sawv cev ua kom dawb hauv kev lag luam textile. Cov ntsev fatty acid ntawm morpholine tuaj yeem siv ua cov tshuaj preservatives. Morpholine kuj tseem siv tau los tsim cov tshuaj pholcodine rau lub paj hlwb hauv nruab nrab. lossis ua cov kuab tshuaj. Diethanolamine siv hauv kev tshuaj xyuas tshuaj ua cov tshuaj reagent thiab cov roj chromatography stationary solution los xaiv khaws thiab cais cov cawv, glycols, amines, pyridines, quinolines, piperazines, thiols, thioethers, thiab dej.

3. Diethanolamine yog ib qho tseem ceeb uas tiv thaiv kev xeb thiab siv tau ua ib qho tshuaj tiv thaiv kev xeb hauv kev kho dej boiler, lub cav txias, roj drilling thiab txiav, thiab lwm yam roj lubricating. Kuj siv rau hauv cov roj ntuj ua ib qho absorbent rau purifying acid gases. Siv ua emulsifier hauv ntau yam tshuaj pleev ib ce thiab tshuaj. Hauv kev lag luam textile, nws tuaj yeem siv ua roj nplua nyeem, tus neeg sawv cev ntub dej, tus neeg ua kom mos thiab lwm yam khoom siv organic synthetic raw khoom.

4. Siv ua cov tshuaj nqus kua qaub, cov tshuaj ua kom yas, cov tshuaj ua kom mos, cov tshuaj ua kom emulsifier, thiab lwm yam hauv cov nplaum. Nws kuj siv ua cov tshuaj nqus cov pa roj acidic (xws li hydrogen sulfide, carbon dioxide, thiab lwm yam) hauv cov roj av, cov roj ntuj thiab lwm yam roj. Nws yog cov khoom siv raw rau kev tsim cov tshuaj, tshuaj tua kab, cov tshuaj zas xim nruab nrab thiab cov tshuaj surfactants. Siv ua cov tshuaj emulsifier rau cov roj thiab cov quav ciab, thiab ua cov tshuaj ua kom mos rau cov tawv nqaij thiab cov fibers hluavtaws hauv cov xwm txheej acidic. Siv ua cov khoom ua kom tuab thiab ua npuas ncauj hauv cov tshuaj zawv plaub hau thiab cov tshuaj ntxuav lub teeb. Nws kuj siv ua cov tshuaj ntxuav, roj nplua nyeem, tshuaj ua kom ci ntsa iab thiab cov tshuaj tshem cov plua plav piston ntawm lub cav.

5. Siv ua tus neeg sawv cev rau kev sib xyaw ua ke rau kev plating nyiaj, cadmium plating, lead plating, zinc plating, thiab lwm yam.

6. Siv ua cov tshuaj reagents analytical, cov roj acid absorbents, softeners thiab lubricants, thiab hauv cov organic synthesis.
